MMA's 10 best pound-for-pound fighters

The pound-for-pound world in mixed martial arts is typically seen through the prism of the "big three" -- Anderson Silva, Georges St. Pierre and Fedor Emelianenko -- and then everybody else. However, Lyoto Machida capturing the light heavyweight mantle raises the question: "Is there room for a fourth?"

Machida's destructive blowout of Rashad Evans to claim 205-pound supremacy was the most brilliant of his career and has left many fans and critics wondering who can beat The Dragon. Regardless of whom the most ideal candidate might be, as the leader of the pack in one of MMA's most talented and star-rich divisions, championship consistency would put the Belem, Brazil, native into rarified air with the sport's other pound-for-pound kings.

It is an active time for MMA's elite fighters, as well. Seven of these 10 pound-for-pound entrants have potential bouts on the slate in the next 10 weeks, making for a fantastic early summer for the sport.
